The standard enthalpy of formation of ethanoic acid :
..[4]
Using Hess's law to calculate :
2 × [1] + 2 × [2] - [3] = [4]
The standard enthalpy of formation of ethanoic acid is -484 kJ/mol.
Answer: The volume in the balloon at the higher altitude is 260 L
Explanation:
The combined gas equation is,
where,
= initial pressure of gas = 760 torr
= final pressure of gas = 511 torr
= initial volume of gas = 233 L
= final volume of gas = ?
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
The volume in the balloon at the higher altitude is 260 L
